The instrument was calibrated using a series of working standards.
A series of working standard solutions of linifanib were prepared by further dilution of the stock solution using acetonitrile.
A series of working standard solutions were prepared by diluting aliquots of stock standard solution with DI water.
All electrospinning processes of PAN solutions were implemented smoothly and continuously under the selected operative conditions, including a series of working temperatures of 20, 40, 60, and 80 °C.
A series of working standard solutions of targets were prepared in the concentration range of 1 1000 μg/mL and analyzed by the LC-ESI-MS/MS method.
The stock solution was further diluted to obtain a series of working standards over the range of 200 1200 ng spot-1 for calibration curve.
This preliminary analysis was followed by a series of working implementations for fingerprints most of which are minutiae-based [64, 65].
Consequently, series of working sessions took place, and consensus of the findings was achieved.
Evidence will be compiled, stored and annotated using a series of working papers.
A series of working standards from 20 100 μg/mL was prepared.
